Hi Paul Mason - In theory it's possible but whether it's practical will likely depend on several factors, not the least of which is the number of students involved.

This question comes up from time to time in regard to dealing with student incompletes in higher ed, and this is prime season for that type of issue. Rather than re-invent the wheel, there is an outstanding description of how this can be handled in Earl Sallade's response in this discussion thread from last year. So if this is your scenario, Earl's description of how it can be handled works like a charm, and is exactly what I do for student incompletes. Basically, you can create sections of the class and assign students to specific sections and give each section a different end date. Again, see that thread for more information.
